Problems solved by technology

[0003] (1) The oil absorption is not large, and the oil absorption ratio is small;
[0004] (2) The selectivity of oil and water is not high, and it often absorbs water while absorbing oil;
[0005] (3) The oil retention is poor after oil absorption, and the oil will leak again after a little squeezing
The oil-absorbing materials prepared in the above-mentioned documents all have good adsorption properties to xylene and carbon tetrachloride, and the maximum absorption ratio reaches 45g / g and 90g / g respectively. Rubber has disadvantages such as low elasticity, poor processing performance, and low raw rubber strength, which lead to poor overall performance of the prepared rubber foam oil-absorbing material, which affects its oil absorption ratio and oil absorption rate.

Abstract

The invention relates to a rubber foaming oil-adsorbing material and a preparing method thereof. The material comprises 100 parts by weight of a mixture comprising natural rubber and polybutadiene, 4-8 parts by weight of N,N'-dinitrosopentamethylenetetramine, 1-8 parts by weight of 4,4'-oxybis(benzenesulfonyl hydrazide), 1-6 parts by weight of sodium hydrogen carbonate, 0.3-0.8 part by weight of diphenylguanidine, 0.2-0.5 part by weight of zinc dimethyldithiocarbamate, 0.1-0.5 part by weight of 2,2'-dithiobis(benzothiazole), 0.1-0.3 part by weight of tetramethylthiuram disulfide, 3-5 parts by weight of zinc oxide, 1-3 parts by weight of stearic acid and 0.5-1.5 parts by weight of sulfur. The material adopts the mixture comprising the natural rubber and the polybutadiene as a substrate and is lower in cost and higher in oil adsorbing rate. The oil adsorbing rate of the material for xylene is 48.6 g / g, and the oil adsorbing rate of the material for gasoline is 30 g / g or above. The method is simple in process and prone to industrial production.

Description

technical field [0001] The invention relates to the technical field of oil-absorbing materials, in particular to a rubber foamed oil-absorbing material and a preparation method thereof. Background technique [0002] In recent years, with the increasing frequency of human activities, accidents such as oil field spills, oil spills from oil tankers, and oil pipeline ruptures have continued to occur, and the continuous discharge of oily waste water has caused serious water pollution. At present, alleviating the pollution problem containing wastewater mainly relies on oil-absorbing materials, which are generally divided into traditional oil-absorbing materials and high-oil-absorbing materials. The oil-absorbing materials used in my country are mainly traditional oil-absorbing materials, such as corn stalks, non-woven wool, kapok fiber, vermiculite, expanded graphite, zeolite, etc. However, traditional oil-absorbing materials mainly rely on physical adsorption or internal capilla...
